Vehicle　motion　simulation　is　an　important　part　of　traffic　scene　simulation,　which　is　helpful　for　urban　road　planning　and　design,　road　capacity　testing　and　other　applications.　Based　on　the　characteristics　of　urban　traffic　scene,　this　paper　studies　the　vehicle’s　movement　behavior.　On　the　basis　of　the　intelligent　car　following　model　based　on　safe　distance,　an　improved　car　following　model　is　constructed　by　adding　acceleration　adjustment　items　which　is　suitable　for　real　urban　traffic　scene.　Besides,　an　improved　vehicle　lane　change　model　is　construct　on　the　basis　of　two-lane　change　model　based　on　acceleration　analysis.　Experiments　show　that　the　two　vehicle　motion　models　proposed　in　this　paper　are　effective　in　simulating　vehicle　stop,　start　and　lane　change　in　urban　traffic　scene.　©　2020,　Springer　Nature　Switzerland　AG.
